5 Revealing Statements from Zuckerberg's Senate Hearing

Here are five revealing statements that came from Mark Zuckerberg during the Facebook founder's testimony before the U.S. Senate on April 10, 2018.

Facebook's biggest mistake: "It was not taking a broad enough view of our responsibility. We focused on just building tools instead of looking to see if tools are being used for good."

On government regulation: Senator's question: "What are we supposed to tell our constituents when they ask us why we should allow you to self-regulate?" Zuckerberg's answer: "I think the real question is, what's the right regulation? Not, whether we should be regulated at all."

Zuckerberg played the humble card: "It was my mistake and I'm sorry. I started Facebook, I run it, and I'm responsible for what happens here."

Not all of the senators bought the apology, however, because about two hours after Zuckerberg gave it, one of the senators displayed a sign of Zuckerberg's previous apologies when Facebook had faced criticism:

The former apologies by Zuckerberg include:

"I'm the first to admit that we've made a bunch of mistakes." - 2011

Also, one senator says he believes Facebook was reckless because the app that got Facebook's data and sold it to Cambridge Analytica had the following terms of service:
